20130033493 | IMAGE GENERATION DEVICE AND OPERATION SUPPORT SYSTEM - An image generation device generates an output image based on input images obtained by image-taking parts. A coordinates correspondence part causes coordinates on a columnar space model arranged to surround a body to be operated to correspond to coordinates on input image planes on which the input images are positioned, respectively. An output image generation part causes values of the coordinates on the input image planes to correspond to values of the coordinates on an output image plane on which the output image is positioned through coordinates on the columnar space model, which is a combination of a plurality of space model parts each having a reference axis. The space model corresponds to a pair of adjacent image-taking parts among the image-taking parts, and an optical axis of each of the pair of image-taking parts intersects with the reference axis of a corresponding one of the space model parts. | 02-07-2013 |
20130033494 | IMAGE GENERATION DEVICE AND OPERATION SUPPORT SYSTEM - An image generation device generates an output image based on a plurality of input images image-taken by a plurality of image-taking parts mounted to a body to be operated. A coordinates correspondence part causes coordinates on a columnar space model, which is arranged to surround the body to be operated and having a center axis and a side surface, to correspond to coordinates on a plurality of input image planes on which the input images are positioned, respectively. An output image generation part generates the output image by causing values of the coordinates on the input image planes to correspond to values of the coordinates on an output image plane on which the output image is positioned through coordinates on the space model. A distance between the center axis and the side surface of the columnar space model is determined in accordance with installation positions of the image-taking parts. | 02-07-2013 |
20130033495 | IMAGE GENERATION DEVICE AND OPERATION SUPPORT SYSTEM - An image generation device generates an output image based on an image obtained by taking images by an image-taking part mounted to a body to be operated, which boy is capable of performing a turning operation. A coordinates correspondence part causes coordinates on a columnar space model, which is arranged to surround the body to be operated and has a center axis, to correspond to coordinates on an image plane on which the input image is positioned. An output image generation part generates the output image by causing values of the coordinates on the input image plane to correspond to values of the coordinates on an output image plane on which the output image is positioned through coordinates on the columnar space model. The columnar space model is arranged so that an optical axis of the image-taking part intersects with the center axis of said columnar space model. | 02-07-2013 |
20130034269 | PROCESSING-TARGET IMAGE GENERATION DEVICE, PROCESSING-TARGET IMAGE GENERATION METHOD AND OPERATION SUPPORT SYSTEM - A processing-target image generation device generates a processing-target image which is an object to be subjected to an image conversion process for acquiring an output image based on an input image taken by an image-taking part. A coordinates correspondence part causes input coordinates, spatial coordinates, and projection coordinates to correspond to each other, the input coordinates being on an input image plane on which the input image is located, the spatial coordinates being on a space model on which the input image is projected, the projection coordinates being on a processing-target image plane on which the processing-target image is positioned and the image projected on the space model is re-projected. | 02-07-2013 |
20130222594 | IMAGE GENERATION DEVICE AND OPERATION SUPPORT SYSTEM - An image generation device generates an output image including a road image based on plural input images that are captured by plural cameras mounted to a body to be operated. The image generation device includes a control part that arranges input image portions of two cameras that correspond to an overlapping area of the image capturing ranges of the two cameras to form a lattice pattern on the output image. The lattice pattern includes as a unit pattern a region that is defined by two circles having a center at the position of a first camera of the two cameras and two circles having a center at the position of a second camera of the two cameras. | 08-29-2013 |
20140362220 | PERIPHERY-MONITORING DEVICE FOR WORKING MACHINES - A periphery-monitoring device for working machines creates an output distance image based on an input distance image taken by a distance image sensor attached to a working machine. The periphery-monitoring device for working machines includes a computer programmed to execute a process including obtaining coordinates on an input distance image plane on which the input distance image is positioned, obtaining coordinates on an output distance image plane on which the output distance image is positioned and associating the input distance image and the output distance image with each other. | 12-11-2014 |
20160005286 | PERIMETER-MONITORING DEVICE FOR WORKING MACHINE - A perimeter-monitoring device has a human presence determining part configured to determine presence or absence of a human in each of a plurality of monitoring spaces located around the shovel and an alarm controlling part configured to control a plurality of alarm output parts that are located in a cab of the shovel and emit an alarm to an operator. The alarm controlling part causes a right alarm output part to emit an alarm when it is determined that a human exists in a right monitoring space, causes a left alarm output part to emit an alarm when it is determined that a human exists in a left monitoring space, and causes a back alarm output part to emit an alarm when it is determined that a human exists in a back monitoring space. | 01-07-2016 |
20160035110 | PROCESSING-TARGET IMAGE CREATING DEVICE, PROCESSING-TARGET IMAGE CREATING METHOD, AND OPERATION ASSISTING SYSTEM - A processing-target image creating device creates a processing-target image based on a plurality of input images. The processing-target image creating device includes a coordinates-associating part configured to associate coordinates on each input image plane on which each input image is positioned, coordinates on a space model onto which each input image is projected, and coordinates on a processing-target image plane, and an. image adjusting part configured to adjust the processing-target image by determining for each input image a re-projection angle of a re-projection line joining the coordinate and the coordinate. The image adjusting part determines for each input image slopes of the re-projection lines such that each coordinate on the processing-target image plane corresponding to an infinity line in each input image corresponds with each other on a dividing line between image parts corresponding to each input image on the processing-target image plane. | 02-04-2016 |
